SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 226,320, dated April 6,1880. Application filed January 17, 1880;

To all whom it may concern Be it known that I, J. B JEwELL, ofCarrollton, in the State of Missouri, have invented a new and ImprovedSliding Window-Blind; and I hereby declare the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, making part of this specification, in whichFigure l is an elevation, showing the inside of the blinds closed. Fig.2 is an elevation of the outside of the blind, showing a portion of theblind cutaway to expose the operating mechanism.

The object of my invention is to provide a device for operating from theinside of the house sliding window-blinds wherein the devices foroperating will hold and bind the shutter to the window-casing; and myinvention consists in sliding shutters on ways outside of the house, incombination with a rackbar and pinion operated from the inside, saidpinion being provided with a flange which lies outside of the rack-bar,as hereinafter more fully described and claimed.

In order that those skilled in the art may make and use my invention, Iwill proceed to describe the manner in which I have carried it out.

In the said drawings, A is the windowframe, and B B the shutters, whichslide on ways a a on the outside of the building. In a recess in eachshutter is set a rack-bar, b, so arranged that a space is left betweenits lower or toothed portion and the wood of the shutter. Through eachside of the window-frame or casing run crank-shafts O 0, provided withoperating handles 6 e, and on their outer ends bearing pinions P P,whose teethengage in the teeth of the rack-bars I). From the outer facesof the pinions, beyond the radial dimension of the teeth, projectflanges I I, which set into the space between the rack-bars and theshutter.

It is evident that as the pinions are turned by the crank-shafts theyfeedback and .forth the rack-bars attached to the shutters, and.

thereby open or close the shutters, as is desired, and that in whateverlocation the shutter may be the flange lying behind the rackbar alwaysacts as a fastening device and holds the shutters to the window-framethrough the medium of the shafts G 0.

Having thus described my invention, what Iclaim as new,'and desire tosecure by Letters Patent, is-

A shutter-operator consisting of a pinion, P, provided with a flange, I,and a crank-shaft, O, in combination with a sliding shutter, B, and arack-bar, I), provided with a space between it and the shutter attachedthereto, as set forth.
